[0058] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0059] With the rapid development of air purification technology, various air systems using air purification technology have been widely used in people's daily lives. Existing air purification technologies, such as electrostatic dust collection technology, are a relatively common air purification technology with diverse application forms that can meet a variety of practical application needs.

[0060] However, existing electrostatic dust collection technology requires a continuously powered module to function properly. This means either a power cord must be connected to an additional power source or a dedicated power outlet must be designed for the electrostatic dust collection module during the design phase. However, existing air systems may not have sufficient power outlets to accommodate the electrostatic dust collection module, thus highlighting the technical limitations of existing electrostatic dust collection methods due to their need for a continuously powered module.

[0061] In order to solve the above technical problems, the present invention provides an air purification method, namely, by configuring an electrostatic dust collecting net that can store electricity in the air system, and then determining the corresponding air quality level according to the indoor air quality actually detected during operation, and then determining the purification strategy based on the specific air quality level, so that the system can control the electrostatic dust collecting net that has stored electricity to output the corresponding voltage according to the purification strategy corresponding to the actual air purification needs, so as to purify the indoor air to different degrees according to different needs. Moreover, since the electrostatic dust collecting net is a filter net that can store electricity, it has the characteristics of short-time charging and long-time operation. Therefore, there is no need to set up a continuous power supply module for it. It can be charged by the original power supply method of the air system and then be powered off for a long period of time. In addition to ensuring the air purification function that the electrostatic dust collection method should have, it also breaks through the technical limitation of requiring continuous power supply, and solves the technical problem that the existing electrostatic dust collection method has the technical limitation of requiring continuous power supply.

[0062] like Figure 1 As shown, Figure 1 It is a schematic diagram of the air conditioner structure of the hardware operating environment involved in the embodiment of the present invention.

[0063] like Figure 1As shown, the air conditioner may include: a processor 1001, such as a CPU, a communication bus 1002, a user interface 1003, a network interface 1004, a memory 1005 and an electrostatic dust collecting net that can store electricity. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The optional user interface 1003 may include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory 1005 may be a high-speed RAM memory or a stable memory (non-volatile memory). The memory 1005 may optionally be a storage air conditioner independent of the aforementioned processor 1001. The electrostatic dust collecting net can be fixed to the air conditioner or can be freely detached, and can optionally be an electrostatic dust collecting net that is self-triboelectric or an electrostatic dust collecting net that can carry a storage material.

[0064] Optionally, the air conditioner may further include RF (Radio Frequency) circuits, sensors, and the like. These sensors may include infrared sensors, air pressure sensors, temperature sensors, humidity sensors, and other sensors. Of course, the air conditioner may also be equipped with other sensors such as a gyroscope, barometer, hygrometer, thermometer, and infrared sensor, which will not be described in detail here.

[0065] Those skilled in the art will understand that Figure 1 The air conditioner structure shown in the figure does not constitute a limitation to the air conditioner, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0066] like Figure 1 As shown, the memory 1005 as a computer storage medium may include an operating system, a network communication module, a user interface module, and an air purification program.

[0067] exist Figure 1 In the air conditioner shown, the network interface 1004 is mainly used to connect to the background server and communicate data with the background server; the user interface 1003 is mainly used to connect to the client (user end) and communicate data with the client; and the processor 1001 can be used to call the air purification program stored in the memory 1005 and perform the operations in the following air purification method.

[0068] Based on the above hardware structure, various embodiments of the air purification method of the present invention are proposed.

[0069] Reference Figure 2 , Figure 2 Schematic diagram of the flow chart of the first embodiment of the air purification method.

[0070] A first embodiment of the present invention provides an air purification method, which is applied to an air system, wherein the air system is provided with an electrostatic dust collection net capable of storing electricity, and the air purification method comprises the following steps:

[0071] Step S10, detecting the indoor air quality during operation of the air system, and determining a corresponding air quality level according to the currently detected indoor air quality;

[0072] In this embodiment, the present invention is applied to an air system, such as an air conditioner, a fan, etc., in which an electrostatic dust collecting net capable of storing electricity is provided. This electrostatic dust collecting net can usually be installed at the air outlet of the air system. Specifically, an electrostatic dust collecting net capable of self-friction charging or an electrostatic dust collecting net capable of carrying a charge storage material can be used.

[0073] Indoor air quality can be measured by one or more indicators. For example, the dust concentration in the environment can be used as a basis for judgment. The air system can use dust sensors to monitor the dust concentration in the environment in real time.

[0074] Taking dust concentration as an example, the system can pre-store a correspondence between specific concentration ranges and corresponding air quality levels. The specific levels can be set to three air quality levels: high dust concentration level, low dust concentration level, and dust-free level. Alternatively, high dust concentration level, medium dust concentration level, low dust concentration level, and dust-free level can be set flexibly according to actual conditions and are not limited in this embodiment.

[0075] Specifically, taking an air conditioning system as an example, upon startup, the air conditioner uses a built-in dust sensor to monitor the dust concentration in the indoor environment in real time. Based on the detected dust concentration, the air conditioner then determines the corresponding air quality level from a pre-stored concentration level mapping. Furthermore, the air conditioner may include a display device corresponding to the dust sensor, displaying the real-time dust concentration value and / or the corresponding air quality level for the user to view at any time.

[0076] Step S20: determining a purification strategy according to the air quality level, and controlling the electrostatic dust collecting net to output a corresponding voltage according to the purification strategy to purify the air.

[0077] In this embodiment, the purification strategy at least includes a purification strategy based on an electrostatic dust collecting network, which can be specifically set to output a certain voltage value within a certain period of time under the current air quality level. Under different air quality levels, the corresponding purification strategies can be the same or different. In addition, in addition to the electrostatic dust collecting network, if the air system is provided with other devices with air purification functions, the purification strategy can also set corresponding strategies for them. For example, while controlling the electrostatic dust collecting network, other air purification devices are also set to output a certain voltage value within a certain period of time and other rules. Purification strategies of different quality levels can be pre-stored in the air system, and the air system can find and implement the corresponding purification strategy according to the current actual air quality level during operation.

[0078] The voltage value output by the electrostatic dust collector according to the purification strategy can be a fixed value, a variable value, or a variable value output over a period of time and then a stable fixed value output, or a fixed value output over a period of time and then a variable value output. The strategy can be flexibly set according to actual conditions.

[0079] Let's take an air conditioner as an example. After determining the air quality level corresponding to the current environment, the air conditioner retrieves the corresponding purification strategy from pre-stored information. Then, according to this purification strategy, it controls the electrostatic dust collector to output the voltage value set in the purification strategy. If the air conditioner determines that the air quality level corresponding to the current environment has changed, it will update the purification strategy and control the electrostatic dust collector according to the newly determined purification strategy. The principle of electrostatic dust removal is that dust-laden gas is electrically separated when it passes through a high-voltage electrostatic field. Dust particles combine with negative ions, become negatively charged, and then discharge toward the anode surface and deposit. Theoretically, the higher the voltage output by the electrostatic dust collector, the stronger its purification capacity.

[0080] It should be noted that if the electrostatic dust collector is not yet charged, it must be charged first (the charging method is the conventional air system method, and no special power supply module and power socket are required). In addition, the filter of the electrostatic dust collector can be a filter with larger pores to avoid large wind resistance that affects the normal air supply of the air system.

[0081] In this embodiment, a chargeable electrostatic dust collecting net is configured in the air system, and then the corresponding air quality level is determined according to the indoor air quality actually detected during operation, and then the purification strategy is determined based on the specific air quality level, so that the system can control the charged electrostatic dust collecting net to output the corresponding voltage according to the purification strategy corresponding to the actual air purification needs, so as to purify the indoor air to different degrees according to different needs. Moreover, since the electrostatic dust collecting net is a chargeable filter net with the characteristics of short-time charging and long-time operation, there is no need to set up an additional continuous power supply module for it. It can be charged by the original power supply method of the air system and can be powered off for a long period of time. In addition, in addition to ensuring the air purification function of the electrostatic dust collection method, it also breaks through the technical limitation of the need for continuous power supply, and solves the technical problem of the existing electrostatic dust collection method having the technical limitation of the need for continuous power supply.

[0082] Furthermore, based on the above Figure 2 The first embodiment shown in the figure provides a second embodiment of the air purification method of the present invention. In this embodiment, the step of determining the corresponding air quality level according to the currently detected indoor air quality includes:

[0083] Step S11, determining a magnitude relationship between the indoor air quality measurement index value and a preset first threshold value and / or a preset second threshold value, wherein the first threshold value is greater than the second threshold value;

[0084] Step S12: If the measurement index value is not less than the first threshold, determining that the air quality level is the first quality level;

[0085] Step S13: If the measurement index value is greater than the second threshold value and less than the first threshold value, determining that the air quality level is the second quality level;

[0086] Step S14: If the measurement index value is not greater than the second threshold, determine that the air quality level is the third quality level.

[0087] In this embodiment, the first threshold and the second threshold can be flexibly set according to actual needs, but the first threshold must be greater than the second threshold. Taking the dust concentration value as an example, the first quality level corresponds to a high-concentration dust environment, the second quality level corresponds to a low-concentration dust environment, and the third quality level corresponds to a dust-free environment.

[0088] As a specific embodiment, the indoor dust concentration PM2.5 can be no less than 25μg / m 3 Classified as a high-concentration dust environment, corresponding to the first quality level mentioned above (i.e. the first threshold is 25μg / m 3);Indoor dust concentration PM2.5 greater than 10μg / m 3 But less than 1025μg / m 3 Classified as a low-concentration dust environment, corresponding to the second quality level mentioned above (i.e. the second threshold is 25μg / m 3 ) ; indoor dust concentration PM2.5 is not greater than 10μg / m 3 Classified as a dust-free environment, corresponding to the third quality level mentioned above (i.e. the second threshold is 25μg / m 3 ).

[0089] For the third quality level purification strategy, the air conditioning system can be set to enter sleep mode. In sleep mode, the electrostatic dust collector can only output a lower voltage or not perform air purification work.

[0090] Furthermore, the air system is further provided with a high-voltage generating device, wherein a first configuration portion of the high-voltage generating device is connected to the electrostatic dust collecting net. If the air quality level is the first quality level, step S30 includes:

[0091] Step S31, determining a first purification strategy according to the first quality level, and supplying power to the high-voltage generating device within a preset time according to the first purification strategy, so that the electrostatic dust collecting net outputs a high-voltage signal that decreases over time based on the first configuration part.

[0092] In this embodiment, the high-voltage generator provides an independent high-voltage output circuit for the electrostatic dust collector. The first configuration portion refers to the portion of the high-voltage generator specifically dedicated to the electrostatic dust collector. The electrostatic dust collector can be connected to the high-voltage generator via its own power contacts. The first purification strategy refers to the purification strategy corresponding to the first quality level. The preset duration can be flexibly set based on actual conditions.

[0093] Specifically, when the air conditioner determines that the current environment corresponds to the first quality level, it means that the air quality at this time is poor and needs to be purified more intensively. The high-voltage generating device is powered so that the high-voltage generating device can provide a high-voltage output circuit for the electrostatic dust collecting network. After the electrostatic dust collecting network is equipped with the high-voltage generating device, it can output a high-voltage signal with a higher initial value that decreases over time according to the first purification strategy, so as to ensure efficient purification while not easily burning the electrostatic dust collecting filter.

[0094] Furthermore, the air system is further provided with an ion generator, and the high-voltage generating device further includes a second configuration part connected to the ion generator. Step S31 includes:

[0095] Step S311, according to the first purification strategy, power is supplied to the high-voltage generating device within a preset time period, so that the electrostatic dust collecting net outputs a high-voltage signal that decreases over time based on the first configuration part, and the ion generator outputs a preset first fixed high-voltage signal based on the second configuration part.

[0096] In this embodiment, since the first quality level corresponds to poor air quality, the air system not only purifies the air through the electrostatic dust collector but also operates in conjunction with an ionizer. The high-voltage generator, through the first and second configuration sections, provides independent high-voltage output circuits for the electrostatic dust collector and ionizer, respectively. The voltage value of the first fixed high-voltage signal can be flexibly set based on actual conditions.

[0097] Specifically, the air conditioner, in accordance with the first purification strategy, powers a high-voltage generator. For 20 minutes, the high-voltage generator configured in the electrostatic dust collector outputs a negative high-voltage signal according to the function V = -(13-t / 2) kV. Initially, the high-voltage signal output is -12 kV, which then gradually decreases with time t (in minutes) until it reaches -3 kV at 20 minutes. Simultaneously, the high-voltage generator configured in the ionizer outputs a negative high-voltage signal of -6 kV (i.e., the aforementioned first fixed high-voltage signal) for the same 20 minutes.

[0098] As a specific embodiment, Figure 3 and 4 shown. Figure 3 This is a schematic diagram of the air purification part of the air system (which can be called an air purification module), which consists of a triboelectric dust removal net 1, an ion generator 2, an electronic control and battery module 3, and an air conditioner indoor unit 4. Figure 3 In the embodiment, a friction electrostatic precipitator 1 and an electronic control and battery module 3 are provided on the indoor unit 4 of the air conditioner, and an ion generator 2 is provided on the friction electrostatic precipitator 1. Figure 4 This is a cross-sectional view of the air purification module, showing the negative ion carbon brush 01, electrostatic dust collection net 02 and outer frame 03. Figure 4 In the middle, the outer layer is the outer frame 03 of the air-conditioning system, and an electrostatic dust collecting net 02 is arranged inside the frame. Above the electrostatic dust collecting net in the frame is the negative ion carbon brush 01 of the ion generator.

[0099] Furthermore, based on the above second embodiment, a third embodiment of the air purification method of the present invention is proposed. In this embodiment, after step S311, the method further includes:

[0100] Step S312: after the preset time period, determining whether the corresponding air quality level changes from the first quality level to the second quality level according to the currently detected indoor air quality;

[0101] Step S313, if yes, determine the second purification strategy, power the second configuration part according to the second purification strategy, and cut off the power to the first configuration part, so that the ion generator can output a preset second fixed high-voltage signal based on the second configuration part, and the electrostatic dust collecting net can output a preset third fixed high-voltage signal based on its own power storage, wherein the second fixed high-voltage signal is lower than the first fixed high-voltage signal.

[0102] In this embodiment, the second purification strategy refers to the purification strategy corresponding to the second quality level. The second fixed high-voltage signal and the third fixed high-voltage signal can be set to the same value or different values, and can be flexibly set according to actual needs. However, the second fixed high-voltage signal must be lower than the first fixed high-voltage signal.

[0103] After the air conditioner executes the first purification strategy for a preset period of time, it determines whether the indoor air quality has improved by detecting the air quality measurement indicators at this time. If the air conditioner determines that the ambient air quality has turned to the second quality level at this time, it means that the air quality has improved under the implementation of the first purification strategy, and there is no need to continue to take the strong purification measures of the first purification strategy. The air conditioner stops supplying power to the first part of the high-voltage generator configured in the electrostatic dust collection net, but continues to supply power to the second part configured in the ion generator so that the ion generator can reduce the output voltage based on the output of the high-voltage generating device and continuously output the second fixed high-voltage signal to weaken the purification intensity. At the same time, since the electrostatic dust collection net has been charged, it can now continuously output the third fixed high-voltage signal through its own stored power to maintain its working state.

[0104] As a specific embodiment, the ion generator can output a fixed negative high voltage of -3kV (the second fixed high voltage) under the second purification strategy, while the electrostatic dust collector can output a stable -3kV (the third fixed high voltage) corresponding to 20 minutes of its own power storage. The high-voltage generator provides a negative high voltage of -2kV to -12kV for the electrostatic dust collector and a negative high voltage of -2kV to -6kV for the negative ion generator.

[0105] Furthermore, after step S313, the method further includes:

[0106] Step S314: when the air quality level corresponding to the currently detected indoor air quality changes from the second quality level to the third quality level, determining a third purification strategy;

[0107] Step S315, powering off the second configuration part according to the third purification strategy to stop air purification, or allowing the electrostatic dust collector to output a preset fourth fixed high-voltage signal based on its own power storage, wherein the fourth fixed high-voltage signal is lower than or equal to the third fixed high-voltage signal.

[0108] In this embodiment, the third purification strategy refers to the purification strategy corresponding to the third quality level. When the air conditioner detects that the indoor air quality has improved from the second quality level to the third quality level during the second purification strategy, indicating that the air quality has further improved, the third purification strategy is initiated. The voltage value of the fourth fixed high-voltage signal is less than or equal to the voltage value of the third fixed high-voltage signal.

[0109] Under the third purification strategy, the air conditioner completely powers the high-voltage generating device, and the ion generator exits the working mode. The electrostatic dust collector can either stop the purification work at this time or output a smaller voltage signal through its own power storage to maintain a non-strong purification function. For example, the electrostatic dust collector can continue the negative high-voltage output of -3kV under the second purification strategy, and can also output a lower negative voltage value than -3kV, such as -2kV, -1kV and other lower voltage values.

[0110] In this embodiment, the ion generator outputs high voltage in the first 20 minutes, which can stimulate a small amount of ozone to sterilize the surface of the purification module. After 20 minutes, the voltage output value is reduced, which can effectively reduce static electricity accumulation and prevent users from electric shock or burning circuits.

[0111] Furthermore, a battery is provided in the air system to control the battery to supply power to the high-voltage generator.

[0112] In this embodiment, the air system is powered by a battery for the high voltage generator. The battery can be fixed inside the air system or freely removed for charging, and is preferably a DC regulated power supply.

[0113] As a specific embodiment, Figure 5As shown. After the air conditioner starts running, it analyzes the indoor air quality at that time. If it is detected that the indoor environment at that time corresponds to a high-concentration dust environment Pmax, the electrostatic dust collection network high-voltage control system based on the electrostatic dust collection network and the negative ion high-voltage control system based on the ion generator are activated in the charging purification mode. In the charging purification mode, the electrostatic dust collection network high-voltage control system adopts a charging dust removal method, that is, the high-voltage generator is powered by a battery, and the high-voltage generator provides a high-voltage output circuit for the electrostatic dust collection network, so that the electrostatic dust collection network outputs a negative high voltage with an initial value of -13kV and a final value of -3kV according to V = -(13-t / 2)·kV within 20 minutes. The negative ion high-voltage control system adopts a strong dust removal method, and the high-voltage generator is powered by a battery. The high-voltage generator provides a high-voltage output circuit independent of the electrostatic dust collection network for the ion generator, so that the ion generator outputs a fixed negative high voltage of -6kV within these 20 minutes. If the air conditioner is activated and the indoor environment is detected to be a low dust environment (Pmin), it enters energy-saving purification mode. The battery only powers the high-voltage generator corresponding to the ion generator. The ion generator outputs a negative high voltage of -3kV based on the high-voltage generator, and the electrostatic dust collector also outputs a fixed negative high voltage of -3kV based on its own stored power. If the air conditioner is activated and the indoor environment is detected to be a dust-free environment (P0), it enters sleep mode, and both the ion generator and the electrostatic dust collector are deactivated.

[0114] After the air conditioner has been running in the charging and purification mode for 20 minutes, the ambient dust concentration at this time is detected. If it is determined through the dust concentration at this time that the indoor environment has turned into a low-concentration dust environment Pmin, the energy-saving purification mode is entered (the specific implementation method is as described above); if the ambient dust concentration at this time still corresponds to a high-concentration dust environment, the original charging and purification mode is continued until it turns into a low-concentration dust environment; if the indoor environment at this time has turned into a dust-free environment, the sleep mode is entered (the specific implementation method is as described above); if the indoor environment at this time has turned into a high-concentration dust environment Pmax, the charging and purification mode is returned to.

[0115] After the air conditioner switches from charging purification mode to energy-saving purification mode, if it detects that the indoor environment has changed from a low-concentration dust environment to a dust-free environment, it enters sleep mode.

[0116] In this embodiment, since the electrostatic dust removal net (such as the friction dust removal net) has the characteristics of short charging time and long working time, the power consumption of the energy-saving purification mode (corresponding to the second purification strategy) is more than 70% lower than that of the charging purification mode (corresponding to the first purification strategy), and the power consumption of the sleep mode (corresponding to the third purification strategy) is more than 90% lower than that of the charging mode. Therefore, by purifying the indoor air to an excellent level within 20 minutes and then switching to the second purification strategy and the third purification strategy, the power consumption is greatly reduced, the ability of the battery to continuously supply power for purification is extended, and the working time of the battery with the same capacity is extended by more than 50%.
